$$(a + b)^3$$

How to Solve the Sum of Two Cube Numbers

Just like for the addition of square numbers we have a formula for addition of cube numbers also.

THE FORMULA IS: $$(a + b)^3 = a^3 + b^3 + 3ab * (a+b)$$

Let us work it out with an example:-

let a=6 and b=8

$$(a + b)^3 = a^3 + b^3 + 3ab * (a+b)$$

$$(6+8)^2 = 6^2 + 8^2 + (3*6*8) * (6+8)$$

216+512+144*14
